How to access role in JSP using spring security?

Question

I want to print a user role in JSP? I know there is a spring -security tag called as <sec:authentication property="principal.username"/> Using this tag I can access the user name..but how to access and print the current role in jsp?

Answer 1

Since principal refers to your UserDetails object, if you inspect that object the roles are stored under public Collection<GrantedAuthority> getAuthorities() { .. }.

That said, if you merely want to print the roles on the screen, do this:-

<sec:authentication property="principal.authorities"/>

Answer 2

Use getAuthorities or write your own implementation of userdetails and create a convenience method.

or :

<sec:authorize access="hasRole('supervisor')">
 This content will only be visible to users who have
 the "supervisor" authority in their list of <tt>GrantedAuthority</tt>s.
</sec:authorize>
